Abstract
The utility model provides a machining device directly clamping a threaded surface without damaging a thread. The technical scheme includes that the machining device comprises a fixture, a taper pin, a piston and a screw sleeve, the piston is movably arranged at the left end of an inner hole of the fixture in a matched manner, an internal thread is arranged at the right end of the inner hole of the fixture, the specification of the internal thread is as same as that of an external thread on a clamped workpiece, the tail end of the taper pin and the screw sleeve are connected and positioned in a threaded manner after the taper pin penetrates the fixture and a radial taper hole in the piston, and the taper pin is concentric with a radial taper hole in the fixture, not concentric with the radial taper hole in the piston and inclined left. The machining device has the advantages that the machining device is simple in structure, easy in clamping and accurate in centering, and the threaded surface cannot be damaged.
Description
Technical field
The utility model relates to a kind of direct clamping flank processing unit (plant) of not damaged screw thread, belongs to clamping tool for machine work technical field.
Background technology
in the time of the screwed axial workpiece in processing end, sometimes need to clamp manufactured flank axle is carried out to turning or grinding, current clamp method is: directly clamp flank, this can damage or plucking flank; Wrap soft bed course clamping at flank, this will cause that Working position precision does not reach requirement, so the clamping of double thread face does not also have a kind of better method at present.
Summary of the invention
The purpose of this utility model is just to provide a kind of direct clamping flank processing unit (plant) of not damaged screw thread, for addressing the above problem.
The technical solution of the utility model is: a kind of direct clamping flank processing unit (plant) of not damaged screw thread, comprise clamp body, taper pin, piston and swivel nut, clamp body endoporus left end arranges piston with movable fit system, clamp body endoporus right-hand member is provided with and the internal thread that is held the external screw thread same size on workpiece, taper pin passes after the radially taper hole on clamp body and piston, its tail end threadably with the swivel nut location that is connected, taper pin is concentric with the radially taper hole on clamp body, and with piston on radially taper hole decentraction and to the left.
The beneficial effects of the utility model are: simple in structure, clamping is easy, and centering does not accurately damage again flank.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Known with reference to accompanying drawing 1, a kind of direct clamping flank processing unit (plant) of not damaged screw thread, comprise clamp body 1, taper pin 2, piston 3 and swivel nut 6, clamp body 1 endoporus left end arranges piston 3 with movable fit system, clamp body 1 endoporus right-hand member is provided with and the internal thread that is held the external screw thread same size on workpiece 4, after the radially taper hole that taper pin 2 passes on clamp body 1 and piston 3, its tail end threadably with swivel nut 6 location that is connected, taper pin 2 is concentric with the radially taper hole on clamp body 1, and with piston 3 on radially taper hole decentraction and to the left.When operation, first the internal thread on clamp body 1 is screwed in to the external screw thread on workpiece 4, then insert taper pin 2, the swivel nut 6 of screwing on taper pin 2 tail end screw threads, because the radially taper hole center line on the relative piston 3 of center line of taper pin 2 is to the left, so taper pin 2 promotes piston 3 workpiece pressing 4 left sides that move right, make workpiece 4 axial location, again clamp body 1 left end is clamped on machine tool three-jaw chuck 7, the right-hand member of workpiece 4 holds out against location by tailstock tool top 5, by adjusting machine tool three-jaw chuck 7, clamp body 1 center is adjusted, after mixing up, center can start processing, add the direction of rotation that will note machine tool chief axis man-hour, so that the direction of cutting force is tending towards clamping work pieces 4, when process finishing, unclamp swivel nut 6, extract taper pin 2, workpiece 4 is easy to be removed.
